Analytic Tools

The project of twentieth-century sociology and political science–to create predictive scientific theory–resulted in few full-scale theories that can be taken off the shelf and successfully applied to empirical puzzles. Yet focused "theory frames" that formulate problems and point to relevant causal factors and conditions have produced vibrant, insightful, and analytically oriented empirical research.

The goal of this book is to describe the most powerful methods for evaluating multiloop Feynman integrals that are currently used in practice. This book supersedes the author’s previous Springer book “Evaluating Feynman Integrals” and its textbook version “Feynman Integral Calculus.” Since the publication of these two books, powerful new methods have arisen and conventional methods have been improved on in essential ways. A further qualitative change is the fact that most of the methods and the corresponding algorithms have now been implemented in computer codes which are often public.
